ELECTRIC VALVE-CONTROLLER..

SPECIFICATION forming part of Letters Patent No. 443,789, dated December30, 1890. Application led Apri1'4, 1890. Serial No. 348,619. (No model.)

To all whoml zt may concern:

Be it known that I, CHARLES E. ONGLEY, a citizen of the United States,residing at New York city, in the county and State of New York, haveinvented an Ilnprovementin Electrical Valve-Controllers, of which thefollow ing is a specification.

The object of my invention is to control a comparatively large valvewhich is moved by fluid-pressure through the agency of a second valve,which is moved bythe power of a magnet in a suitable electric circuit;and the invention consists` in certain arrangements and combinationshereinafter described and claimed.

The accompanying drawing is a central section through the apparatus.

1 is the main valve, and 'consists of a central stem provided at eachend with a screwthreaded extension. On the lower extension is acup-shaped piece 2, carrying a suitable packing, which when the valve isclosed rests against the valve-scat 3. The cup, and hence the packing,is of greater diameter than the valve-seat, so that the packing restssquarely and firmly thereon. The extension also carries a lock-nut 4.AAround a socket in the cap into which the extension projects, andpressing up against the cup 2, is a coiled spring. On the upperextension of the valve is a second cup-shaped piece, which is preferablylarger than 2, and which fits as a piston into the tube 5. This cupisprovided with a packing 6. Over the piston-head 7 is a washer or packing8, preferably of leather, and over this a retaining-nut 9 and lock-nut10. Through 7, 8, and 9 are holes placed in line and preferably providedwith a hollow serew-threaded bushing 1l, which serves as a permanentexhaust for the purpose hereinafter described. A branch pipe 11 isattached to the chamber under the piston and conducts the escapingwater. The upper end of the tube 5 is closed by a nut-cap 12, which mayhavev a cock attachment, as also may the tube below the second valve.The valve is normally held up against the seat 3. by the spring.

13 is the water-inlet. When the valve mechanism. is attached to awater-supply, water flows into the space 14 below the main valve andinto the space 15 below the second valve.

The Water-pressure then combines with the spring to hold the main valveclosed.

The second valve in the preferred form consists of a stern 16, whichpasses through a packing to the outside of the valve-chamber. At theinner end of lthe stem is a cup-shaped nut with a packing 17 and withlocking-nuts. This valve is held closed by spring 18, and when there iswater in the space 15 by waterpressure. Stem 16 carries a nut 19, havingon its upper side a socket 20, into which socket passes loosely a rod2l, which is supported in a bearing E22 andbushingfl. A pin 21 rides ina slot 25 in the upper end of the bushing as the rod moves up and down.This serves to prevent the rod from turning, and thus keeps the armature2G carried thereby in line with the magnet-poles.

27 is an arm or bracket having atits upper end an adjusting-screw, andbetween a nut thereon and the armature is a spring 28, the

tension of which is opposed to that of spring 18 and the water-pressure,but 'is insuicient to overcome the latter. The magnet 20, only 011e limbof which is shown in the drawing, may be in any desired circuit. If, forexample, the outlet-pipe 30 leads to the normallyempty house-pipes in afire-extinguishing system, the circuit might run through and to thethermostat of such a system, or it might run to the oice or other pointwhere an alarm would be received and where the person in charge couldoperate a circuit-controller manually, if he found it necessary; but Ido not claim, specifically, these uses of the valve, and I do not limitmyself to such uses.

The operation of the apparatus is as follows: XVhen the valve mechanismis in place, water under the desired pressure occupies the space belowthe valves, and when the circuit of the magnet is closed or varied by athermostat, by hand,or otherwise the armature, co-operating with spring2S, opens the second valve, admitting water to the space above thepiston-head of the main valve. This head being larger thanV the oppositeone the valve is moved, thus allowing water to pass from the inlet-pipedirectly to the outlet-pipe 30 and to the place of use. The main valvewill be held in this position as long as thc circuit IOC is maintainedin operative condition. From the space above the main valve waterescapes through the hollow bushing sufficient rapidityto prevent thewater-pressure from moving the valve. The object of this escape istorelieve the pressure above the valve after closure of the secondvalve, so that 4a further downward movement of the valve,

and to provide for this movement is the 0b ject of making thevalve-stern and the armature-carrying rod in two parts connected looselyat the socket 20. In order to get the desired power from themagnet tooperate the valve, the armature is placed quite near to the poles andwhen attracted is brought against the poles. Notwithstanding this fact,the valve can be still farther moved by hand or otherwise, owing to theloose connection described. l

It. will be clear that the arm 27 and spring 28 may be omitted, provideda magnet of suffcient strength is employed. Certain other of thefeatures described may be varied without departing from my invention.

Having thus described my invention,wl1at Il claim is-` 11, but not with;

1. The combination, with a main valve operated by Huid-pressure andcontrolling the passage between an inlet and outlet pipe, of a secondvalve. controlling a passage leading from the inlet-pipe to a spaceabove the main valve to'open it, a magnet, an armature for the magnet,to which is connected a rod, and a valve-rod for the second valvemeeting the the armature-rod, but having no positive connectiontherewith, whereby the valve and rod may be moved by the armature orindependently thereof, substantially as described.

2. The combination, with a valve held closed by Huid-pressure and aco-operating spring, of a magnet and co-operatin g spring for openingthe valve and -a loose connection between the valve-stem and thearmature-rod, substantially as described.

3. Theicombination of a valve and stem, a spring holding said valveclosed, a rod loosely connected to the stem, movable in a bearing, andcarrying an armature, a magnet, a bracket, one end of which terminatesadjacent tothe armature, and a springA between the bracket and armatureand r(zo-operating with the magnet, substantially as described.
